Align OF_getencprop_alloc API with OF_getencprop and OF_getprop_alloc Change OF_getencprop_alloc semantics to be combination of malloc and OF_getencprop and return size of the property, not number of elements allocated. For the use cases where number of elements is preferred introduce OF_getencprop_alloc_multi helper function that copies semantics of OF_getencprop_alloc prior to this change. This is to make OF_getencprop_alloc and OF_getencprop_alloc_multi function signatures consistent with OF_getencprop_alloc and OF_getencprop_alloc_multi. Functionality-wise this patch is mostly rename of OF_getencprop_alloc to OF_getencprop_alloc_multi except two calls in ofw_bus_setup_iinfo where 1 was used as a block size.

Clean up OF_getprop_alloc API OF_getprop_alloc takes element size argument and returns number of elements in the property. There are valid use cases for such behavior but mostly API consumers pass 1 as element size to get string properties. What API users would expect from OF_getprop_alloc is to be a combination of malloc + OF_getprop with the same semantic of return value. This patch modifies API signature to match these expectations. For the valid use cases with element size != 1 and to reduce modification scope new OF_getprop_alloc_multi function has been introduced that behaves the same way OF_getprop_alloc behaved prior to this patch.

The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Enable using ofw_bus_find_compatible in early platform code Before this patch function ofw_bus_find_compatible was using memory allocations in order to find compatible node and the property's length. This way there was always a suited buffer for property, however this approach had also disadvantages - ofw_bus_find_compatible couldn't be used when malloc is not available, e.g. during fdt fixup stage. In order to remove the usage limitation of ofw_bus_find_compatible(), this patch modifies the function to use ofw_bus_node_is_compatible() (instead of the one without _int suffix), which uses a fixed buffer on stack instead of dynamic allocations.

Replace multiple nearly-identical copies of code to walk through an FDT node's interrupts=<...> property creating resource list entries with a single common implementation. This change makes ofw_bus_intr_to_rl() the one true copy of that code and removes the copies of it from other places. This also adds handling of the interrupts-extended property, which allows specifying multiple interrupts for a node where each interrupt can have a separate interrupt-parent. The bindings for this state that the property cells contain an xref phandle to the interrupt parent followed by whatever interrupt info that parent normally expects. This leads to having a variable number of icells per interrupt in the property. For example you could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>. Differential Revision: https://reviews.freebsd.org/D803
